The aim of the present study was to compare competitive anxiety and perceived overtraining in athletes with and without anabolic steroids consumption. The statistical population included all athletes of team and individual sport fields in Tehran city in 2016. 251 male athletes with and without anabolic steroids consumption were selected using multi-stage cluster sampling method. Athletes had mean age (24 ± 6) years and exercise history (3 ± 1) years. Data were collected using competitive anxiety and perceived overtraining questionnaires. The findings were analyzed by multivariate analysis of variance (MANOVA) and independent t test and showed that athletes without the consumption of anabolic steroids had higher cognitive and physical anxiety than those athletes who consumed anabolic steroids, but there was no significant difference between the two groups in self-confidence. Also, given the perceived overtraining variable, the group who did not use anabolic steroids had a higher level of overtraining. The results indicated that one of the main reasons why athletes use anabolic steroids is their benefits which reduce the negative states and improve the mental and physical performance. That is why these steroids prevail among athletes every day.

The purpose of this study was to determine the effect of instruction intellectual biorhythm feedback on the movement Performance of the students were athletes and non-athletes. The case studies were selected in access style include 144 male and female student athletes and non- athletes with an average age of 21.5 years. They were divided in 2 groups of athletes and non- athletes and each of the groups under three different conditions biorhythm cycle (intellectual biorhythm peak, intellectual biorhythm Peak + feedback, control) in pre-test and then randomly divided into 6 groups and Participated in 3 times in motor function test. The data were analyzed in pre-test by one-way analysis of variance (ANOVA) test and to comparing different groups by Mix ANOVA with repeated measure test on a plot (2*3*3) and to identify differences by Bonferroni post hoc tests in a significance level p

The Competitive State Anxiety Inventory (CSAI-2) is the most widely used instrument to measure competitive anxiety in the literature. The aim of this study was to examine the factorial validity and reliability of Persian version of Competitive State Anxiety Inventory-2 regarding intensity, direction, and frequency dimensions. The original form included 27 questions and 3 subscales including somatic anxiety, cognitive anxiety, and self-confidence. 356 questionnaires were completed by 16-34-year-old athletes who took part in different sport fields. Five competing models were used to estimate construct validity of the inventory. Confirmatory factor analysis was conducted to contrast the proposed models. The inventory reliability was calculated using the internal consistency method. To examine temporal reliability, intraclass correlation coefficient was applied using test–retest method. The results showed that the Persian version of the inventory supported the 16-item 3-factor model in intensity, direction, and frequency dimensions; thus, validity and reliability of the inventory were confirmed. In conclusion, Persian version of Competitive State Anxiety Inventory-2 with 16 items is recommended to measure athletes' state competitive anxiety.

Attribution theory is one of the psychological dynamic theories that explainsand describes people's perception of facts. Therefore, the aim of this research wasto study success and failure attributions in athletes and coaches. The population ofthis study consisted of athletes and coaches of national teams (elite) and clubteams (sub–elite) in swimming, badminton, karate, taekwondo, table tennis andwrestling. 120 male players and 12 coaches were selected through multistageconvenience sampling method. Then, data were collected by attribution stylesquestionnaire (ASQ). The data were analyzed by multivariate ANOVA at P˂0.05.The findings showed that elite athletes expressed more unstable and specificattributions in failure conditions. In contrast, sub–elite athletes expressed morestable and general attributions in failure conditions (P≤0.0001). As well, thecoaches of elite athletes expressed more stable and specific attributions than thecoaches of sub–elite athletes in success dimension (P≤0.0001). The results showedthat the casual attribution of athletes (elite and sub-elite) and their coaches (eliteand sub-elite) expressed elite athletes and coaches' privilege as elite athletesexpressed that most of the reasons for their success were internal, stable andgeneral. Also, athletes and coaches stated different attributions in the samesituation. It is recommended that coaches encourage their athletes to attempt moreto express all of their competencies in the competitions.
